Enamel Erosion

  • What is enamel erosion?

    Enamel erosion occurs when your tooth enamel, the outer, translucent protective layer of your teeth, wears away, which can cause you to experience tooth sensitivity. Enamel wear can happen as a result of teeth grinding, aggressive brushing, or an acidic diet. Once enamel wears away, it cannot grow back.

    Not sure if your teeth are at risk? Let's find out if Sensodyne toothpaste is right for you.

  • What causes enamel wear?

    Over time, frequent daily intake of acidic foods and drinks—such as fruit juices, carbonated drinks—can wear away your tooth enamel. This is also known as acid erosion. Other causes of enamel wear include teeth grinding and aggressive brushing.

    To help protect your teeth against enamel erosion, talk to your dentist and use a fluoride toothpaste specially formulated to help strengthen tooth enamel.

  • Can enamel erosion cause sensitive teeth?

    Yes. Enamel is the hard, protective surface of the tooth. Over time, if tooth enamel wears away, it exposes the inner layer known as dentine. This can cause tooth sensitivity as the protection the enamel provides to the tooth and the nerves inside is reduced. This is why, if you have enamel erosion, eating ice cream or sipping hot soup can be painful.

  • Why should I use a Sensodyne mouthwash?

    Used with Sensodyne toothpastes and toothbrushes, Sensodyne Cool Mint Mouthwash is part of a good overall oral care plan. It is suitable for people with sensitive teeth, it has a no-alcohol formula, a mild mint taste and fluoride to help fight tooth decay.

  • Where can I purchase Sensodyne toothbrushes?

    Sensodyne toothbrushes are available in the oral care section of most major pharmacy and grocery retailers.

  • Can Sensodyne be dabbed on a sensitive tooth?

    Sensodyne Rapid Relief can be dabbed on for relief at 60 seconds* (when used as directed). For other Sensodyne varieties, there is no clinical evidence to support dabbing as an effective means of application.

    *apply a pea-sized amount to a clean finger-tip and rub gently into each sensitive area (max twice per day) for 1 minute before brushing.
